Operating Heater With A Temperature Sensor - Xylem SI Analytics SLR Mode D'emploi

24 Initial Operation

3.3 Operating heater with a temperature sensor

Connecting the temperature sensor
Switching on the heater
Actual temperature 24° C
Selecting the command temperature
Command temperature 78° C
Connecting the temperature sensor

Be sure to
(see "6 Accessories").
 Connect the temperature sensor at the rear of the laboratory
stirrer.
 Make sure that the cable of the temperature sensor is routed so
that it cannot touch the heating zone.
 Immerse the temperature sensor into the liquid min. 30 mm in
depth.
In contrast to operation without temperature sensor, the laboratory
stirrer now features:
 Automatic temperature control instead of fixed heating stages
with control of energy.
 Temperature display alternating between command temperature
and actual temperature instead of showing the heating stages.
Switching on the heater
 Press and hold the right control knob for approximately
2 seconds until the heater display appears.
 The display shows the actual temperature measured by the
temperature sensor at that time.

Select your desired command temperature within 30 seconds.
 After 30 seconds the heater switches off again if you do not
select a command temperature (safety function).
Selecting the command temperature

Select the desired command temperature using the right control
knob (turn clockwise to increase temperature). The maximum
command temperature is 200°C.
 The selected command temperature is shown on the display
(indicated by dots between figures).
 The bar graph indicates the heating activity of the heater.
 The heater heats up and maintains the selected temperature.
 The residual-heat indicator "HOT" continues to light up as long
as the glass-ceramics heating zone is still hot.
CAUTION! Risk of burning!
Do not touch the heating zone!
 The display now alternates between command temperature (with
dots between figures) and actual temperature (no dots between
figures) every 5 seconds.
